Abstract: Rehabilitation of edentulous ridges using dental implants is the most demanding and sought-after treatment modality with patients and dental surgeons.

The presence of adequate width and height of bone is pertinent for successful installation and osseointegration of dental implants and we have come a long way to compensate the width of defective ridges for implant installation.

Horizontal bone augmentation using ridge split technique was first introduced by Dr. Hilt Tatum almost three decades ago. Although there are many methods for ridge correction horizontally, the ridge split and expansion remains the most widely preferred.

In this script we would like to share our experience of ridge split and simultaneous implant installation technique in over 57 cases.

This technique is associated with high success and survival rates of 95-97%. Studies by Crespi et al 2015 success rate was 97%, Santagata et al 2015 & Tang et al 2015 showed 93.2% and 95.6% success rate respectively. Therefore, the ultimate objective is restoration of functional requirement.
Summary: For a successful outcome of implants a stable placement is pertinent, the minimum alveolar bone should be larger 6mm to ensure the circum-implant bone width of at least 1-1.5mm.

Tooth extraction often leads to considerable bone resorption during the healing stage rendering the loss of ideal bone width.

When managing severe bone deficiency in the horizontal width of alveolar ridges the use of GBR techniques alone can be limited or challenging, although block grafting is a defi
